Abstract (en)

[origin: EP1659007A2] The present invention relates to an air suspension and an electronically controlled suspension system. The air suspension comprises an air piston installed between a vehicle body and an axle of a vehicle to absorb a vibration or shock that the axle receives from a road when the vehicle travels; a rubber tube airtightly coupled to an upper end of the air piston to function as an air spring; a cap airtightly coupled to an upper portion of the rubber tube; a volume expander connected to the inside of the rubber tube to expand a pressure acting volume of the air spring; and a volume control valve for opening or closing the connection between the inside of the rubber tube and the volume expander to determine the pressure acting volume of the air spring. According to the present invention, there is an advantage in that when a lateral motion occurs at the vehicle mounted with the air suspension, a spring rate of the air spring is controlled to rapidly and efficiently stabilize the movement of the vehicle.
